Xanthosoma : Greenhouse Plants
T – tropical, minimum of 18°C (65°F)
These exoticmust have warm humid tropical conditions to grow well. A light peaty well-drained and careful watering is essential. It is all too easy with these tropical plants to damp them down to such an extent that they become waterlogged and will rot. It is particularly important in this case as these plants are tuberous. This is an advantage if, for instance the temperature drops leading to the foliage turning yellow and falling off. With care, the tubers can be moved to a warmer place, kept only just moist and coaxed back into growth. However, while growing healthily there is no need to induce a dormant period by drying plants out. Xanthosoma lindenii has deep green leaves with the veins outlined in striking ivory-white. It grows to about 60 cm (2 ft) in height. X. violaceum from the West Indies will make a huge and glorious plant given optimum conditions, growing easily to 1.2 m (4 ft) high. Huge heart-shaped leaves look very exotic but the most striking features are the stems which are violet coloured and almost glisten with a sort of bloom. Plants will produce offsets which can be used for propagation.
